Precautions

Please read before use.

Thank you for purchasing the SBS-2003 Digital Hydrometer.
Please read and follow the below instructions carefully.

Warning!

• When measuring toxic substances, be well aware of its
properties and put on protective gloves, goggles, etc.

• The electrolyte contains sulfuric acid and is toxic. Burns
may occur if contact is made on the skin or clothes.
Blindness may occur if contact is made to the eyes. Always
wear protective glasses and rubber gloves. If the electrolyte
is splashed onto the skin or clothing, rinse with sufficient
amounts of cold water. If it gets into the eyes, flush with
cold, clean water for a minimum of 15 minutes and seek
immediate medical attention.

Caution!

• Care should be taken to avoid damage to the prism. Use soft tissue
paper when wiping the prism surface to avoid scratching. Never use
any metal tools or abrasive materials on the prism.

• The instrument is designed to measure the electrolyte solution of lead
acid batteries. Do not use for the measurement of other electrolyte
solutions such as in alkaline batteries. (i.e., NiCd, LIOH, NMH)

• Remove the battery from the instrument before storing for long periods
of time.

Note

• Read this manual carefully to understand the operation and functions of the instrument.

• Make sure that the instrument is calibrated correctly by zero-setting daily before taking

measurements.

• Handle the product with care. Do not drop the instrument or expose it to a strong shock.

• SBS will not be held liable for any damages or injury resulting from any improper or

unintended use of the instrument.

• SBS will not be held liable for any damages or injury resulting from the qualities and
characteristics of samples measured with this instrument.

Note about Temperature

Attention to the following note is needed during measurement when the
temperature of the electrolyte varies greatly from the ambient temperature:

The SBS-2003 compensates for the temperature of the sample automatically
by detecting the temperature on the prism in the Sample Chamber. If the
temperature of the sample is different from the prism temperature, wait
approximately 3 seconds for every 1°C℃ (2°F) of the difference between
temperatures before pressing the START key. (If very large differences in
temperatures are suspected, allow time for the sample to warm the prism
before pressing the START key.)

ERRATIC READINGS OR ERRORS

When the SBS-2003 seems to be malfunctioning or out of order, check the battery
power first. Malfunctions can often be solved by simply replacing the battery.

• The SBS-2003 does not have a power switch. Once the battery is
inserted the electric circuit of the SBS-2003 is on. Remove the battery
from the instrument before putting it into long-term storage.

• Any generic 9V battery can be used.

• Always zero-set the instrument after the battery is replaced.

• When the voltage of the battery is low, replace with a new one.

6. Zero-setting

Caution!

• The SBS-2003 needs to be zero-set at the
beginning of each day. Moreover, each time the
ambient temperature changes while in use, it
needs to be zero-set.

• Zero-setting is also needed whenever the
battery is replaced.

• Allow 30 to 60 minutes for the instrument to be
acclimated to the ambient temperature.

1. Remove the sample tube cap.

2. Have distilled or de-ionized water ready.

3. Press the START key to turn on the SBS­2003, then press the SELECT key to
move the triangular pointer to “Temp.” or
“S.G.”(Figure 9)

4. Submerge the tip of the sample tube in
water. Squeeze and then release the tube
pump. Water is drawn up into the sample
chamber. (Figure 10)
